Important Tip

Stiebel Eltron hot water heaters should only be installed or serviced by licensed installers.These are not do-it-yourself appliances.

Please hand this Operation and Installation Manual and hand over to the home or building owner when theinstallation is complete.

Operating Instructions for the User and the Technician

1. Operation and Service

1.1 Start-upThe boiler (39) and solar storage tank (30) after installation, constitute a functional unit (refer Diag. 4 and 5).Hot water is generated throughout the year by the solar collectors.

The entire heater and hot water system must be filled with water and have good air ventilation. Please, refer to the solarcollector’s and the boiler’s installation instructions.

2. Maintenance and CleaningRoutine care and maintenance extends the life expectancy and operating safety of the hot water storage unit.The outer casing should be cleaned with a slightly damp cloth and commercially available neutral cleaning agent, thisshould be done on a regular basis

2.1 Membrane Safety ValveThe proper function of the safety group (28), especially of the membrane safety valve (21) is very important to preventdamage to the hot water storage unit. The membrane safety valve needs to be monitored for functionality during cold-water addition (27). The water has to flow from the drip line at full stream.

The discharging water can be hot!

2.2 DecalcificationWith hard tap water, a deposit of scale will form on the inside of the storage unit. Based on professional experience, it isnecessary to decalcify with commercially available solvents at timely intervals. Follow the manufacturers instructions forsolvent use. The hot water storage unit needs to be emptied. The revisions flange at the storage bin must be dismantledand sediments on the tank bottom must be removed.

2.3 Exchange of the Safety AnodeDepending on the composition of the tap water, an inspection of the safety anode (Pos. 1, Diag. 1) at more or less timelyintervals is recommended. With heavy wear, an original equipment replacement anode (refer Ch.6.8 and Ch.7 ) must beinstalled to protect the inner container from corrosion. An inspection should be performed at least once a year.

3. Failures – Causes – Correction

Failures Causes CorrectionInadequate water pressure Shut-off valve is not completely open. Cold

or hot water line is obstructed.Open Shut-off valve. Clean or exchangepipes.

Hot water flow inadequate Boiler temperature gauge is set too low.Recommended 80-85°C.Heat exchanger is calcified.

Set boiler temperature gage to recommendedtemperature. Clean heat exchanger.

Hot water storage tank notbeing heated

Program selection at the heater gage is notproperly selected.

Select and set program per instructions.

Outlet quantity inadequate Perlator at the extraction point blocked. Unscrew perlator and clean.Hot water supply too fastexhausted

Flow rate too high. Recommended 2.6-3.9gal./min.

Restrict Spigot valve rate.

6. Set-up and Installation

6.1 Set-upInspect the packaging for damage and remove packaging preferable only at the installation site.

For the selection of the installation site, the tare weight of the storage unit (unit and insulator) including the fill-waterweight must be considered. The room has to be above freezing. For drainage, the water drainage pipe must be freezeproof.

6.2 ConnectionRefer to Diag.1 and Diag. 2.

6.3 Heater InstallationThe installation of the heating circuitry is shown in Diag. 4. The heater installation can be according to the installationdiagram. This, however, varies according to operation. In addition, it must be assured that no air can collect in thesystem. Therefore, an exhaust unit has to be built into the heating circuitry (31).

6.4 Hot Water Installation6.4.1 Prior to installation check that the local conditions are compatible with the appliance design, especially that themaximum working excess pressure of 145 PSI (10 bar.) can be maintained.

6.4.2 A steel or a copper pipe with insulation can be used for the hot water connectors. Copper pipe with insulation isespecially suitable because of its low friction and heat loss.

Required combination

Cold water pipeline Hot water pipelineCopper pipe copper pipeSteel pipe steel or copper pipePlastic steel or copper pipe

6.4.3 A safety group (28) must be installed into the cold water supply (27, Diag. 4). The order of the individual fittingsmust be in accordance to local regulations.

6.4.4 The membrane safety valve (21) has to be set to 145 PSI (10 bar.) excess pressure and sealed. It can only beinstalled into the cold water supply (27). The supply has to be thoroughly inspected prior to installation. Installation of dirtfilters or any other narrowing of the supply line to the membrane safety valve is forbidden.

The membrane safety valve (21) has to be easily accessible. Expansion water generated during the heating has to flowvisibly into a funnel and be drained.Funnel and drainage pipe must be large enough to accommodate water drainage with a fully opened membrane safetyvalve. The drainage pipe must be protected from freezing and must not lead outdoors.

The membrane safety valve (21) has to be set such that there are no water drips with the resting heater (storage waterbeing reheated).

Heavy dripping of the membrane safety valve on the outside of the warming operation can be caused by dirt in the valveseat of water pressure that is too high. At excessive water pressure a pressure reducer (25) needs to be installed.

6.4.5 During installation all necessary screws outside of the flange area must be in order. This assures that the revisionflange can be maintained.

6.4.6 Drainage of the hot water tank (30) is via the drainage faucet (29) at the drainage connector.

6.4.7 The circulator can be attached to a separate socket across the thermometer. Drill the outer casing with a hole saw∅ 50 where marked and remove insulation from the socket in that area.

For energy conservation, use of a circulator is not recommended.

Diag. 56.5 Hot water temperature probe

6.5.1 The hot water temperature probe is to be installed into the immersions sleeve (Pos. 3 Diag.1) of the hot waterstorage tank.Then the connector pipe for heater regulation has to be installed and attached to the clamps of the low voltage plug asdescribed in separate operation and installation instructions for the regulator.

6.6 Solar Storage Tank – Temperature Probe

The solar storage tank temperature probe must be attached to the immersion sleeve of the hot water storage tank (Pos. 6Diag. 1).The temperature probe must be inserted into the probe sleeve until its dead stop (Ill.6). The compressed flat rod has tobe inserted until set with the spring struts in the front.Then the connector pipe has to be laid according to solar regulator SOM 6K, SOM 6/3D or SOM 7/2 and attached to theclamps of the low voltage plug as described in separate operation and installation instructions of the regulator.

Diag. 6 Diag. 7

6.7 Connection to the Solar UnitThe installation of the solar circuitry is shown in Diag. 5, page 12. The solar circuitry installation can follow the installationdiagram. This differs depending on the application.

Refer to the separate operation and installation instructions for the solar collector SOL 25 S.

Test operation after installation. Start up must follow the approval of the installer (refer operation and use).

6.8 Signal anode (spare part)If a signal anode is installed into the SBB … K SOL storage tank, the following installation of the signal anode must beobserved:Installation – signal anode• Pull out the red shut-off plug while simultaneously depressing the pressure ring, Diag. 6a. on page 13.• Push in the open pipe end of the indicator element until dead-stop, Diag. 6b.• Attach the sticker “Note Signal Anode” to a highly visible spot on the insulation.

When the storage tank is not operated with a signal display, the red plug must remain in the anode!

Function – Signal Anode(Safety Anode with usage display)

• After consumption of the anode, humidity escapes through the hollow anode core to the signal cartridge and causes acolor change there (refer Diag. 7)

• When the cartridge turns red contact the installer so he can check the anode and if needed replace it.

6.9 Screw-in unit BGCBGC is screwed into a 1 “ bushing into the front side of the storage tank. This is then locked with a 4-corner plug SW22.As an alternative the bushing can be dismantled with a 12-corner nut SW26.The installation instructions of the screw-in heater must be observed.

7. Tips for the User

Routine maintenance improves operating safety and life expectancy of the solar hot water storage tank SBB … K SOL.
